In addition to several dozen never before seen cars, this year’s Detroit auto show will include a new Nissan display with a 150 foot halo, the largest Toyota display ever and a new 30,000 square-foot atrium.

For Detroit Mayor Dave Bing, who toured Cobo Center today, the renovations at the convention center and the rebounding automotive industry were enough to make him long for his days as an automotive supplier.

“I’ll tell you what, I have mixed emotions,” said Bing, who owned a steel stamping company called Bing Steel before he became mayor. “There is a feeling in your gut that says, you know, I miss this.”

Official press conferences for the 2013 North American International Auto Show begin Monday and it opens to the public on Jan. 19. It is among the largest auto shows in the world.

Bing, who is presiding over a city on the brink of a potential bankruptcy, said the city should draw inspiration from the automotive industry and the Detroit auto show, which have both bounced back from stark times during the Great Recession.

“This has been an unbelievable transformation,” Bing said of the auto show and renovations at Cobo Center. “Cobo is ready for the world, and pretty soon, Detroit is going to be, again, ready for the world.”

David Tillapaugh, Ford’s auto show manager, said the Dearborn automaker is displaying an original 1948 F-1 pickup truck and will be emphasizing its truck lineup at the show.

“We continue to introduce new features, new technologies, and we have plans for the future that are really exciting,” Tillapaugh said. “There are going to be some surprises at the show.”

Nissan, borrowing a trick used by high-end luxury retailers and hotels, plans to pipe its own distinctive scent called The Vert Oriental into its display area.

A team of global executives reviewed several possible scents from several companies before deciding on the smell, said Erich Marx, Nissan’s director, Social Media and Interactive Marketing for Nissan North America.

Vert Oriental is a delicate aroma that captures the essence of green tea scent during Chinese spring harvest, according Nissan’s scent supplier.

“At Nissan, we feel like this is an opportunity to experiment,” Marx said. “Just like high-end retailers and high end hotels, there is an opportunity to have a Nissan scent.”

Nissan also will debut a new auto show stand with a 150 foot long halo that appears to float over a stadium seating-style stage.

The new display, designed and constructed by Auburn Hills-based George P. Johnson, will be featured at 10 other global auto shows this year.

“We really wanted to have the stand debut in the midst of our five new vehicles in 15 months and the timing was right, from a launch cadence standpoint, to introduce it in Detroit,” Marx said.

Nissan is planning to reveal a redesigned hatchback version of its Nissan Versa and at the show under the name Nissan Versa Note to align it with the global identity of the subcompact car. Nissan also is planning to reveal a new mid-size crossover concept vehicle that is likely to fors-shadow the redesign of the Murano.

Toyota and Lexus also are going big at this year’s auto show.

The 35,000-square-foot Toyota exhibit is larger than previous Toyota stands at NAIAS. With the additional square footage, Toyota has made way for 34 vehicles, such as the 2013 editions of the all-new Avalon and RAV4, as well as an assortment of displays that highlight the automaker’s recent successes and promising future technologies.

But by far the biggest new feature will be a new 30,000-square-foot glass atrium.

The atrium is part of a $279-million upgrade of Cobo Center. While work on the atrium isn’t complete, a number of events will still occur there.

Those events will include the first press conference on Monday as well as the ribbon cutting ceremony for Charity Preview on Jan. 18.

Bob Shuman, co-chairman of the 2013 show, also said Michigan Gov. Rick Snyder is expected to speak in the atrium and various events also will be held there.

“This is the first time we’ve had it available,” Shuman. “This is what the rebirth of Detroit is all about.”
